Preheat the oven according to package instructions for wonton wrappers.

In a mixing bowl, combine the thawed spinach, chopped artichoke hearts, cream cheese, shredded pepper jack cheese, shredded mozzarella cheese, minced garlic, and crushed red pepper flakes. Mix well.

Take a wonton wrapper and place a spoonful of the filling in the center. Moisten the edges with water, fold, and seal the wonton.

Repeat the process until all the filling is used.

Place the filled wontons on a baking sheet and bake according to the wonton wrapper instructions until golden brown and crispy.

Garnish with fresh chopped parsley before serving.
